The maps work on pretty much any Garmin mapping unit. There are some issues relating to POI and address searching on some Nuvis. Since he already has the GPS he can download and try it out at home. If he has problems searching his best starting place are the forums at the link you posted.

It was a bit fiddly but we managed to load the maps okay. But for some reasons there are no POI's. And then it took some time for the unit to lock onto the satellites the first time but since then it's been going well.

Almost makes you think you could get a cheap Garmin off ebay and then load free NZ maps on it and two country's maps available.

I guess that you loaded the maps using MapSource? If so, you may have clicked on the map tiles one by one, using the map selection tool? In that case you couldn't select the POI maps.

There are two ways to load the maps into the unit:

1. Using MapSource (or Basecamp) press M to pick the map tool, then draw a box around the area you want. On the left there is a map tab and in there you should see the POI tiles listed if you did it right.

2. Download the gmapsupp.img file instead and copy it straight onto the unit (or memory card). That way you have all maps loaded, but you can't use them in MS (not sure about Basecamp here...).

And then it took some time for the unit to lock onto the satellites the first time but since then it's been going well.

That's normal.

Yes, you can. Not sure about the last 4 words in your last sentence...

I wasn't clear I guess. If you buy a US Garmin you have US maps. Then you can load NZ maps using the maps discussed here. If you go back to the US you can reload the US maps. I am not sure you have both on at the same time - possibly with a large SD card but my friend's unit only had internal memory.

OK, I bought my Zumo in the US and it has the N Am maps installed. When plug it into the PC and look on the unit in the garmin folder the biggest file there is called gmapprom.img, about 1.2 GB. This is most of the preloaded maps. When you load additional maps they go into a file called gmapsupp.img. Now, if there isn't enough room for the NZ maps (unlikely, as they are a lot smaller) then I can move the big file onto the PC before loading the new maps. When I'm finished I simply delete the new file and copy the old one back (leaving the copy on the PC as a backup. In fact, it's a good idea to back up the whole garmin folder.)
